A search for sources of the detritus of the Ordovician sandstones from Sol-Iletsk block (Hole Ordovician 2) based on the first data of the geochemical and Lu/Hf-isotopic systematic of zircons

Abstract

The first isotope-geochemical and geochemical characteristics (the “TerraneChrone” method) of previously dated (U-Pb, LA-ICP-MS) detrital zircons from Ordovician sandstones (borehole Ordovician-2, Sol-Iletsk block) are presented. A comparative analysis of the characteristics of the studied zircons and the corresponding characteristics of the complexes composing the possible feeding provinces is carried out.
